I suspect you need a platform where plain 'char' is unsigned, so that 'typedef
yytype_uint8 yy_state_t;' is treated as if it were 'typedef char yy_state_t;'
which means yy_state_t indexes provoke the diagnostic. (A GCC bug, if you ask me.)

I approximated the problem on x86-64 by manually replacing the typedef with
'typedef char yy_state_t;'.
